Default 2.2t vs. 2.2 n/a crank

Does anyone know the strength differences between the two, and should it just drop in? I spun a bearing in my 91 ss 2.2t and am looking at my options. I have a 2.2 (out of a 93 legacy L) n/a complete motor on standby and for the moment I just need this car back on the road. I do plan on building this motor up, but the time isn't right just yet. Any info wil be greatly appreciated. I did read through a bunch of threads using search also....

There's no difference. You can also use a crank from an Ej18 in there. They're the same.

With very few differences, all phase 1 cranks (except EJ25) are the same.

The only one I know for a fact is different is the early Legacy RS/RA, which was hand balanced. Even at that, it is most likely the same forging as all the others. There may be others from Impreza RAs, but not sure. Anything you will find in a North American vehicle is exactly the same.

For phase 2 motors there are a few different cranks, mostly to do with factory oiling improvements.

For phase 1 EJ25 cranks the stroke was increased from 75mm to 79mm. The rod journal diamer was decreased from 82mm to 78mm. I know little about phase 2 EJ25 cranks so I won't comment.

Thanks for the info guys. I actually made a decision last night to satisfy my original intentions. I'm going to just install the whole n/a motor (swapping over cams and intake manifold) and put my tdo4 and tmic on it and run at low boost. Meanwhile I'll still be able to have the car on the road and build the 2.2t block on the side.
